Matt Yglesias points to two altnerative takes on the NYC subway map, which you can find here and here. The first — used by the MTA until 1972 — sacrifices geographical consistency for cleanness of lines, and so makes for a very useful subway map but doesn’t map to the real world above ground very well. The second is a nicer hybrid of the current version and the more abstracted original.
It goes to show that maps are very context dependent: you reall have to think about what your overall goals are for disseminating the information. If you want people to be able to find their way once they get out of the subway station — or get a sense of how far they have to walk once they emerge — that puts different constraints on the design.
